Analysis and comparison of two high-frequency reference rectifier test methods

In the process of using the LED transparent screen, after a long time, the product will inevitably require irregular maintenance. Many people are very unfamiliar with the concept of LED transparent screens, but at present, LED transparent screens have been gradually used in high-end office buildings, commercial complexes, shop windows and other places in the city center. So, how to maintain the LED transparent screen? In the process of daily maintenance of the LED transparent screen, the following points need to be paid attention to:

How many daily maintenance methods do you know about LED transparent screens?

1. Keep the power supply stable, and the grounding protection is good, try not to use it in harsh natural environments! (Such as strong thunder and lightning weather);

2. It is strictly prohibited to enter water, iron powder and other easily conductive metal objects in the screen. The transparent led display should be placed in a low dust environment as much as possible. Large dust will affect the display effect, and too much dust will cause damage to the circuit;

3. If water enters due to various reasons, please cut off the power immediately and contact the maintenance personnel until the display board in the screen is dry before use;

4. If there is dust on the surface, please separate it from vacuum cleaners and air gun facilities (do not use rags, etc. to wipe directly, and do not use force to prevent the screen from falling off);

5. For normal maintenance, use vacuum cleaners and air guns to remove dust. Do not use too hard or rough cloth or dirty cloth to wipe to prevent damage to the product surface;

6. It is recommended that the LED display has a rest time of more than 2 hours per day, and the LED display should be used at least once a week during the rainy season. Generally, turn on the screen at least once a month and light it for more than 2 hours;

7. The led display screen needs to be regularly checked whether it is working properly and whether the line is damaged. If it does not work, it should be replaced in time, and the line should be repaired or replaced in time if it is damaged;

8. Don't stay in full yellow, full red, full green and other full bright screens for a long time during playback, so as to avoid excessive current, excessive heating of the power cord, damage to the LED light, and affect the service life of the display. Do not disassemble or splice the screen at will;

9. If the internal circuit of the led display is faulty, non-professionals are prohibited from touching it, so as to avoid electric shock or damage to the circuit; if there is a problem, please professional personnel to repair it.

In addition, the daily maintenance of the LED transparent screen is also very important. Regularly clean the dust accumulated on the screen to avoid affecting the heat dissipation function. When playing advertising content, try not to stay in all white, all green, etc. for a long time, so as not to cause current amplification, cable heating and short-circuit faults. When playing festivals at night, the brightness of the screen can be adjusted according to the brightness of the environment, which not only saves energy, but also prolongs the life of the LED display.
